How do I study POI density in OSM?

2

Given the question: Which location has the most of a specific POI mapped in OSM per area? If I load OSM data into PostgreSQL, can it answer that type of query?

A more specific example would be "Where in the US does OSM contain the most park benches per square mile?"

That kind of question is generally answered with a "heat map" or "hot spot" analysis in GIS (Geographical Information System) terminology.

QGIS or ArcGIS can do that for you, once you have the data in some kind of GIS ready format (database or shapefile):

QGIS - Heat Map plugin: http://docs.qgis.org/2.0/en/docs/user_manual/plugins/plugins_heatmap.html

ArcGIS - Optimized Hot Spot Analysis (Spatial Statistics): http://resources.arcgis.com/en/help/main/10.2/index.html#//005p00000058000000
